COLUMBIA, Mo. –  Methicillin-resistant Staphylococcus aureus (MRSA) infections are caused by a type of staph bacteria that has become resistant to the antibiotics used to treat ordinary staph infections. The rise of MRSA infections is limiting the treatment options for physicians and surgeons. Now, an international team of researchers, led by Elizabeth Loboa, dean of the University of Missouri College of Engineering, has used silver ion-coated scaffolds, or biomaterials that are created to hold stem cells, which slow the spread of or kill MRSA while regenerating new bone. Scientists feel that the biodegradable and biocompatible scaffolds could be the first step in the fight against MRSA in patients.
